The server will be moved to a different location in the datacenter tomorrow.
Bob will be moved 10 meters down the datacenter to meet with other servers and hopefully make new friends in his new rack.
The server will be down from 9AM AEST and will hopefully be back up shortly afterwards. I'll keep this post updated with info.
In the meantime maybe check out SkyHub at: hub.sky-mc.net
Update: Bob has been moved!
